White Plains, New York, December 21, 2016 —
Although CoQ10 and ubiquinol are among the most popular supplements, wide variations in price, dosage, absorption and bioavailability can make choosing the right product a difficult task. To help, ConsumerLab.com recently purchased 18 popular CoQ10 and ubiquinol supplements, testing to see whether they contained their claimed amounts of CoQ10 or ubiquinol, and carefully comparing quality and cost.
ConsumerLab.com discovered one product contained just 78% of the amount of CoQ10 listed on the label, a finding which was confirmed in a second independent laboratory. Even among products that contained their claimed amounts, the suggested daily serving size of CoQ10 ranged from 50 mg to 400 mg, and the cost to obtain an equivalent amount ranged from 7 cents to $1.07. The cost to get the same amount of ubiquinol, the "active" form of CoQ10 which tends to be more expensive, ranged from 27 cents to $1.16. Many of the reviewed products include compounds such as polysorbate 80 or black pepper extract to enhance their absorption and/or bioavailability but, as discussed in the new review, they may also cause side-effects and drug interactions. Among products which passed ConsumerLab.com's tests of quality, several were identified as CL's Top Picks
, for providing quality CoQ10 or ubiquinol at lowest cost.
CoQ10 is the third most popular supplement (behind fish oil and multivitamins) in the U.S. among people who use multiple supplements, according to a 2015 survey by ConsumerLab.com
of over 10,000 supplement users. CoQ10 appears useful in treating congestive heart failure and preliminary evidence suggests additional uses including improving "vitality," reversing side-effects of "statin" drugs, and preventing migraine headaches.
